direct kinematic problem是什么意思

网络释义

用法例句

In this paper,we use addition theory on the Abelian group to study two problems on the Abelian group, the direct problem ,that is, let A and B, what are properties and the structure of the sumset A+B? , and the inverse problem- when |A+B| is as small as possible, what are properties and the structure of the set A and the set B?The main work of this paper has three aspects.

本文应用加性理论，讨论了关于阿贝尔群(Abelian)的两个问题，一个是直接问题：已知A与B，和集A+B的构造与特性是什么?另一个是逆问题：当|A+B|较小时，A与B的构造与特性是什么?我们主要做了三个方面的研究：首先，我们介绍了一个关于整数和集的直接问题与逆问题的新结论；其次，讨论了|2A|在几种特殊情形下的计算；最后，我们应用关于阿贝尔群(Z_a_0，+)的加法数理论，在两种特殊的情况下我们改进Vitek’s界和Shen Jian’s界，从而获得关于的Frobenius数的一些新的估值公式。
